Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-459	The product does not properly "clean up" and remove temporary or supporting resources after they have been used.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in Google Chrome's Browser component. A use-after-free occurs when a program continues to use a pointer after freeing the memory it points to. In this case, a remote attacker could exploit this by crafting a malicious HTML page to execute arbitrary code inside the browser's sandbox.

Detection Guidance

Detection of CVE-2026-113073 requires checking the version of Google Chrome installed. If your version is prior to 156.0.8078.47, the system is vulnerable. Use commands like 'google-chrome --version' or 'apt list --installed | grep chrome' to verify the installed version.

Impact Analysis

This vulnerability could allow an attacker to run malicious code on your device through a specially designed webpage. Since it executes inside the sandbox, it may bypass some security restrictions, potentially leading to unauthorized access or control of your system.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (health data security) by potentially exposing sensitive user or patient information.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use after free vulnerability in the browser.
